SMOKE-JACK.

PECIFICATION forming part of Letters Patent No. 357,941, dated Februaryl5, 1887.

Application filed June l2, 1886, Serial No. 204,913. (No model.)

T0 all whom t may concern:

Be it known that I. ANDREW W. QUAOKEN- BUSH, of the city of Peru,countyof Miami, and State of Indiana, have invented certain new and usefulImprovements in Smoke-Jacks, of which the following is a specilication.

AS is Well known mund-houses for engines are provided with pipes whichextend through the roof, and upon the lower ends of these pipes areordinarilyadjustable portions having iiaring lower ends, which iit overthe tops of the smoke stacks of the locomotives and are known as smokejacks. Heretofore the means employed for elevating and lowering thesesmoke -jacks has usually consisted of chains running over pulleys andextending to the side of the house, which are not only in convenient butexpensive.

rlhe object of my invention is to provide a cheap, convenient, andinexpensive device to take the place of such chains and pulleys foroperating the jacks. This object is accomplished by pivoting a leverupon the stationary part of the smoke-pipe, connecting one end by meansof an appropriate link to l the smoke-jack and attaching to the otherend a handle by which it may be operated.

The invention further consists in means for securing this lever inposition, and thus holding the smoke-jack at the desired elevation, saidmeans in this case being shown as a weight which automatically shiftsits position as the lever is moved up and down, and thus serves to holdthe smoke-jack up when the lever is down, as will be hereinafter moreparticularly described.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a perspective view of the pipe, smokejaek and my improved means foroperating the latter, the connection between the smoke-jack and leverinside the pipe being indicated by dotted lines; Fig. 2, a detailsectional view looking toward the right from the dotted line 2 2 in Fig.l; Fig. 3, a view on a somewhat enlarged scale of the handle; and Fig.4, a transverse sectional view vof the lever as seen when looking to theleft from the dotted line 4 i in Fig. l.

In said drawings, the portions marked A represent the permanent portionof the smokepipe; B, the smoke-jack; C, the lever; D, the weight, and Ethe handle.

The pipe A is the ordinary pipe, secured in the roof of the engine-houseor round-house. lt has a bearing, a, secured thereto for the pivot ofthelever. The smoke-jack B is also substantially ofthe ordinaryconstruction, and its straight portion preferably iits inside the lowerend of the pipe A. It is preferably provided with appropriate ears, b,which extend up and approach each other at the upper end inside; or itmay instead have the ears secured to the outside, if the lever isarranged to operate on the outside.

The lever Gis mounted on a pivot, c, in the bearing a, and preferablyextends through a slot in said bearing and said pipe A to the inside oi'said pipe, where it is connected by means of a pivot, c', to the link C.on the smoke-jack B. This link C has several holes in its lower end,and is connected to the ears B on the smoke-jack B by means of a pivot,b, which extends through holes in said ears and one ofthe holes in thislink. lThus it may be connected at either of several points, and theelevation of the smoke-jack thus varied at pleasure.

rlhe weight D is preferably in the form of a ball, and rests on the topof the lever C, being held thereon by guide-rails D', secured to saidlever, or some other appropriate means, such as apipe or troughshapedway. The lever is so arranged, as shown, that when it is pushed up theinner end is lower than the outer end, and consequently said ball willroll toward said inner end,when the weight of the smokejack willoverbalance that of the weight and lever and hold said lever down. Whenit is desired to raise said smoke-jack, however, thc outer end of saidleveris pulled down until it is at a lower level than the inner end,when the ball will roll to said outer end and overcome the weight of thesinol e-jacl ,whiel1 is thus held at its elevated position, and the pullon the handle can then be released.

rEhe handle E is mainly a rod connected to the outer end of the lever bya pivot, e, as shown, and is provided with an appropriate hand-hold, E.It may be divided into two parts, as indicated, the lower partconsisting of a tube or pipe having a slot in its side, and the upperpart of a rod extending inside said IOS tube, and its lower end having aprojection, e', extending through said slot. N otches e2 e3 are formedalongside said slot in said tube at its upper and lower ends,respectively, and thus the handle may be made longer or shorter to theextent of the length of said slot by sim ply giving the tube a partialturn on the rod,

moving said tube the length of said slot and reversing the turn, so thatthe projection e will rest in one or the other of the notches.

Having thus fully described my saidinvention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination of the pipe, the smoker 5 jack, and a lever pivotedto saidpipe and consmoke-jack will overbalance said weight and lever andkeep its lowest position, and when said weight is at the outer end ofits path of movement it will overbalance said smoke-jack and hold it inthe elevated position.

3. The combination, with the lever C for operating the smoke-jack, ofthe handle E, consisting of a rod having a projection and a tube placedupon said rod and provided with a slot and notches in the side of saidslot, whereby said handle may be shortened or lengthened, as desired.

4. The combination of the pipe A, having bearing a, the smoke-jack B,having ears B', the lever C, mounted on a pivot in said bearing A., alink, C, by which said lever and the ears on the smoke-jack areconnected, and means of operating said lever,substantially asdescribed.Y
